Technical Paper Round-Up: July 5


New technical papers added to Semiconductor Engineering’s library this week. [table id=36 /] Semiconductor Engineering is in the process of building this library of research papers. Please send suggestions (via comments section below) for what else you’d like us to incorporate. If you have research papers you are trying to promote, we will review them to see if they are a good fit for... » read more

Univ. of Manchester & Shandong Univ.–Synaptic Transistors


Research paper titled "Synaptic transistors with a memory time tunability over seven orders of magnitude" from researchers at The University of Manchester (UK) and Shandong Technology Center of Nanodevices and Integration, School of Microelectronics, Shandong University, China. Abstract "The human brain is capable of short- and long-term memory with retention times ranging from a few second... » read more

Interfacial ferroelectricity in marginally twisted 2D semiconductors


Abstract "Twisted heterostructures of two-dimensional crystals offer almost unlimited scope for the design of new metamaterials. Here we demonstrate a room temperature ferroelectric semiconductor that is assembled using mono- or few-layer MoS2. These van der Waals heterostructures feature broken inversion symmetry, which, together with the asymmetry of atomic arrangement at the interface of tw... » read more

Week In Review: Design, Low Power


Tools Vtool released a new version of its Cogita visual debug platform. New features aim to provide faster debug capabilities, including visual representation of test results using log files as input, improved manipulation and navigation throughout big logs, ML algorithms to classify data and find the relationship between inputs, and the ability to merge and compare test flow of two different ... » read more

Manufacturing Bits: June 8


Maskless EUV lithography At this week’s 2020 EUVL Workshop, KJ Innovation will present more details about its efforts to develop a maskless extreme ultraviolet (EUV) lithography technology. Still in R&D, KJ Innovation’s maskless EUV technology involves a high-numerical aperture (high-NA) system with 2 million individual write beams. The 0.55 NA technology is targeted for direct-write l... » read more

Periodic table for molecules In what could propel the development of new materials, the Tokyo Institute of Technology has developed a periodic table for molecules. If the proposed concept is developed and adopted, the table could one day be used for creating new materials. It also may predict new materials for future use. This table is somewhat akin to the periodic table of elements, wh... » read more

Simulating quarks and gluons The U.S. Department of Energy’s Oak Ridge National Laboratory is simulating sub-atomic particles on the world’s most powerful supercomputer. The system is simulating these particles at speeds over 70 times faster than the predecessor. More specifically, Oak Ridge is simulating quarks and gluons on the recently-announced Summit supercomputer. In simple terms,... » read more

Computers that mimic the human brain According to a group of researchers led by the Jülich Research Centre in Germany, a computer built to mimic the brain’s neural networks produces similar results to that of the best brain-simulation supercomputer software currently used for neural-signaling research. The custom-built computer named SpiNNaker, which the team said has been tested for ac... » read more

Some superconductors carry spin currents A few years ago, researchers from the University of Cambridge showed that it was possible to create electron pairs in which the spins are aligned: up-up or down-down. The spin current can be carried by up-up and down-down pairs moving in opposite directions with a net charge current of zero, and the ability to create such a pure spin super-current is an... » read more

Chipmakers Look To New Materials


Graphene, the wonder material rediscovered in 2004, and a host of other two-dimensional materials are gaining ground in manufacturing semiconductors as silicon’s usefulness begins to fade. And while there are a number of compounds in use already, such as gallium arsenide, gallium nitride, and silicon carbide, those materials generally are being confined to specific niche applications. Tran... » read more
